Struct StaticMemory 

Source 
pub struct StaticMemory { /* private fields */ }
Expand description

This is an internal-only api.

A static memory allocates 6GB of virtual memory when created in order to allow the WebAssembly module to contain no bounds-checks.

Additionally, static memories stay at a single virtual address, so there is no need to reload its address on each use.

Static memories take a relatively long time to create, so if memories are short-lived, it’s recommended that a dynamic memory is used. There is currently no user-facing api that allows them to select the type of memory used however.
